Contact Form 7[resolved] Contact Form 7 - how do I make fields "required" (3 posts)

The name and email fields are already required, as indicated by the (required) next to the field titles. However, I've gotten forms sent to me that ONLY have those fields entered. I need the Subject and Message Body required also, but obviously just adding (required) next to them doesn't translate into actual code. Any help would be appreciated!

<p>Subject (choose one)
[select* Subject include_blank "Technical Issues (video not playing, PDF not downloading)" "Content Issues (mistake found on text of website, videos, or documents)" "Feedback About Site or Program (positive or negative)" "Testimonial (Tell us why you've enjoyed the program or our customer service)" "Question" "Suggestion for Further Instruction" "Other"] </p>
